There are few artists whose work and personality are as fascinating as those of Marcel Duchamp (1887-1968). As the inventor of the readymade who boldly declared an everyday object a work of art, he revolutionised art history and paved the way for conceptual art. His seminal works and writings continue to have an enormous impact on contemporary artistic practice. For the first time, the Staatsgalerie Stuttgart is presenting its extensive Marcel Duchamp holdings and the appurtenant Serge Stauffer Archive in an exhibition. Seminal pieces from the Staatsgalerie’s collection, among them the "Bottlerack", the painting "Study for 'The Chocolate Grinder No 2'" and the window object "La Bagarre d’Austerlitz", will be shown alongside a selection of international loans. The display is complemented by a unique archive put together by the Swiss artist and Duchamp researcher Serge Stauffer (1929-1989). The exhibition is the first to present the ‘100 Questions’ Stauffer wrote to Duchamp in 1960 as part of their correspondence. Duchamp’s ‘100 Answers’ offer important insights into the artist’s intellectual and creative practice and bear witness to the depth of Stauffer’s exceptional research.
